Mifflin-St Jeor Equation:

\[ BMR_{men} = 10 \times weight + 6.25 \times height - 5 \times age + 5 \] \[ BMR_{women} = 10 \times weight + 6.25 \times height - 5 \times age - 161 \] \[ TDEE = BMR \times activity\ multiplier \]

1. What is the TDEE Calculator?

The TDEE (Total Daily Energy Expenditure) Calculator estimates your daily calorie needs using the Mifflin-St Jeor equation based on Mayo Clinic guidelines. It calculates both your Basal Metabolic Rate (BMR) and total energy expenditure based on your activity level.

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor equations:

\[ BMR_{men} = 10 \times weight + 6.25 \times height - 5 \times age + 5 \] \[ BMR_{women} = 10 \times weight + 6.25 \times height - 5 \times age - 161 \] \[ TDEE = BMR \times activity\ multiplier \]

Where:

\( weight \) — Body weight in kilograms (kg)
\( height \) — Height in centimeters (cm)
\( age \) — Age in years
\( activity\ multiplier \) — Based on activity level (1.2-1.9)

Explanation: The equation provides an accurate estimate of your basal metabolic rate and total daily calorie needs based on your personal characteristics and activity level.

3. Importance of TDEE Calculation

Details: Knowing your TDEE is crucial for weight management, whether your goal is weight loss, maintenance, or muscle gain. It helps determine appropriate calorie intake for your specific needs.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, age in years, select gender and activity level. All values must be valid (weight > 0, height > 0, age between 1-120).

5. Frequently Asked Questions (FAQ)

Q1: Why use Mifflin-St Jeor equation?
A: The Mifflin-St Jeor equation is considered one of the most accurate BMR formulas and is recommended by Mayo Clinic and other health organizations.

Q2: What is the difference between BMR and TDEE?
A: BMR is the calories your body burns at complete rest, while TDEE includes all daily activities and exercise.

Q3: How accurate is this calculator?
A: While highly accurate for most people, individual variations in metabolism may affect results. Use it as a starting point and adjust based on your progress.

Q4: Should I use metric or imperial measurements?
A: This calculator uses metric measurements (kg and cm) for optimal accuracy with the Mifflin-St Jeor equation.

Q5: How often should I recalculate my TDEE?
A: Recalculate every 4-6 weeks or whenever your weight changes significantly or your activity level changes.
